To @ZZ whom it may concern:

Be it known that l, ROBERT W. Jnss, of Riverton, in the county ofSangamon, and in the State of Illinois, have invented certainI'mprovements in Lubricating Oar-VVheels; and Ido hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which- Figure l is aperspective view of my wheel. from the outer side. Fig. 2 is a like Viewof the same with a portion of the hub broken away to show the interiorconstruction. Fig. 3 is a central section upon an axial line, and Fig. 4is a section upon a line with the plane of rotation. u

Letters of like name and kind refer to like parts in each of the igures.Y

The design of my invention is to give to a ear wheel and axle a maximumof efficiency and durability by insuring a constant and sut`- cientsupply of oil to their bearing-surfaces; and to this end said inventionconsists, principally, in the construction of the oil-recess within thehub of the wheel, substantially as and for the purpose hereinafterspecied.

It consists, further, in the special construetion of thewheel and itscombination with the axle, substantially as and for the purposehereinafter shown.

In the carrying into practice of my invention I employ a car-wheel, A,of any usual pattern, and within its hub aform an annular recess, c',that entirely surrounds the central bearing portion,a2. The rear end ofsaid part a unites with and forms part of the inner end of said hub; butat its outer end the former is connected with the adjacent portion ofthe latter by a number of lugs or braces, a3, which extend radiallybetween said parts. The inner or axle-bearing portion, a2, extends,preferably, to or near the outer face of the wheelA, While the hubproper, a, extends outward an inch or more beyond said Wheel-face andforms a continuation of the recess or chamber c.

The axle B has the usual form of axlearm, b, which is adapted to fitinto the axial opening in the wheel A, with the collar b at its innerend contained within a suitable recess, a, at the inner end of the huba, and its outer end projecting sufficiently beyond the bearing portiona to permit of the insertion therein of a pin or key, G, that operatesto lock said axle and wheel in relative positions. For the purpose ofenabling said key to be placed in or removed from position, theprojecting portion of said hub c is provided with an openby a pivotedcap or other equivalent means. 4

From said chamber oil is permitted to pass to the bearing-surface of theaxlearmb by means of a number of openings, ci, that pass radiallythrough the bearing. portion a2 and furnish communication between theinterior of the latter and said chamber.

As constructed it will be seen that the bearings of the wheel andaxle-arm are surrounded by oil which cannot escape from its chamber, andby the movements of said wheel is caused to circulate freely throughorbetween the bearing-surfaces. In order to break or arrest the flow ofsaid oil around the outer side of .-its chamber in consequence ofcentrifugal force, Iprovideatthreeor more points around the innerperiphery of said chamber a radially inward projecting anges as, whichextend from the rear end of said chamber to a point upon a line with theouter end of the bearing portion c2.

The wheel described is cast in one piece by coring out its oil-chamber,and only requires that its axial opening, the outer end of its bearingportion a2, and the collar-recess a4 be dressed with suitableeasilyfoperated tools, and the openings a5 and c formed in order to fitsaid wheel for use.

Having thus fully set forth the nature and merits of my invention, Iclaim- 1.
